Sending Email from HTML Using ASP.Net

Personally I would have the form POST to a HTTP handler (they end in .ashx) which does the processing in ASP.NET. From this handler you can read in the passed fields from the form and send an e-mail via your SendEmail() method.

For example, in your HTML:

<form action="email.ashx" method="POST">
    <input type="text" name="email" />
    <input type="text" name="content" />
    <button type="submit">Submit</button>
</form>

Then a HTTP handler:

public class EmailHandler : IHttpHandler
{

    public void ProcessRequest(HttpContext context)
    {
       string email = context.Request.Form["email"];
       string content = context.Request.Form["content"];

       SendEmail(email,content);
    }

    private void SendEmail(string address, string content)
    {
        ...
    }

}

This is very rough but gives you a little more to go on.

there are a couple different ways you can do this:

1. You can modify the action of your form to point to a .aspx page and then in the code behind of that page you can catch the request and send the email from there. ( this would be similar to sending to a HTTP handler ). The http handler would give you greater performance than the .aspx page.

2. You can perform an ajax call on submit of your form that will then pass the form data to a web method that would then send the email. This will require you to create an .asmx service to be called from the javascript.
